I didn't know this until recently: there is different sizes of spheres, and that, the smaller ones read higher if used out or range. they determine the size needed by watts, and amp draw.

they have 3r,6r,12r, and the massive 24r.

we should be testing 250 watts in a 12 foot radius, not a 6 or a 3. that's a big piece of equipment.

so TBH, I don't think its that important, I think SF, par/spec readings by a good meter(s) is good enough.

this may sound strange, but I trust a uncut video, over some black-n-white lab PDF

true. I have been in discussions with a testing company. They want $550 for "distribution and color ( sphere ) test"
I think just using the board figures that out. I was looking at the light over my two SIP containers and I have a shelf next to the containers and I noticed the light is well distributed there so I put a prt of the pepper plant there and it is happy.
Experience is the best test along with a good PAR meter like you said.

The growth rate is good.
So good I had to move a Sensi Star into the "fattening area" today.
The other 3 will get moved on Sunday.
The boards seem to be doing "exactly what it said on the tin"......... Grow plants!
Lol
Wappa in front, Strawberry Banana back left, Sensi Star 2 back right.

Original Sensi Star now in fattening area under 250 watts o Cree cxbs 3500k

@Moflow what is the "flattening area"? Are you going to SCROG her out?

Lol......
FATTENING AREA.
Where I put the plants into another room with lots of light to finish off.
The 32 x 32 tent with the growgreen boards at 100 watts each for late veg, early flowering - up to week 4 of flowering and when they get too big into the "fattening room" for last 4/5 weeks.
I hope that clears up any confusion....... :bigjoint:​

I have been in discussion with Jeff and he hears from Samsung told me the 3000k LM571C is going to go into reduced production making them less available and more expensive.
I will continue using 3000k as long as possible and then I am going to start using that new 3200k. Lol.

I am considering if prices change leaning towards the 2700k or the 4000k.

I will keep folks informed.

There are few fixtures that have the ability to mix spectrum most have a single spectrum 3500k 5000k 6500k etc. Having to spectrum to mix gives greater flexibility and production focus without the expense of specific colors reds and blues as well as IR and UV.
